PVC Filter Pressure Gauges & Switches


Orange Research has been a supplier of PVC filter gauges and switches for water and corrosive liquids applications for over 20 years.  Now they’ve expanded the line to add more features.  The primary wetted parts are PVC, Teflon for compatibility with water and liquid chemicals.  They’re perfect for difficult environments where aluminum, stainless steel or brass is not appropriate.  They’re very popular in water purification systems.

With standard differential pressure ranges from 0-10 to 0-30 psid, they handle the bulk of filter applications.  Other ranges are available upon request.  The PVC filter gauge bodies handle up to 200 psi pressures.  Metal pressure bodies are optional to handle up to 3000 psi line pressures.

The dials made from durable ABS plastic, measure up to 3.5″ diameter.  Switches are standard options to alert users of alarm conditions and transmitters are also available upon request.  Accuracy is 2% and 5% F.S. and each unit is calibrated to NIST standards.  The units come with 1/8″ or 1/4″ female NPT process ports.  Manifold mounting ports are also available. C-clamps are available to mate to panels.
